My Sharp Aquos 32 inch has a blinking red light, it's been like that for weeks. A technician came to our house and tried to fix it and he said nothing was wrong. For about 2 hours the TV worked but when we turned it off and then tried to turn it on again, the blinking red light came up again. How do I turn it on?

Hi.

Easy fix do the following.
Set is in factory mode. To remove follow these steps below extracted from the service manual.

1. Unplug the AC power cord of TV set to force power off.
   
2. While holding down the “VOL (–)” and “INPUT” keys on the set at once, plug in the AC power cord to turn on the set. The letter K should have disappeared from the screen.

The problem is most likely the the screws are loose on the inverter boards. The screws must be tighted as they provide the ground to the inverter bds. The inverter boards are undet the shields on both sides of the unit after pulling the back cover. One way to make sure that you are losing back lights and not video is when your picture goes black, shine a flash light on the screen at an angle and will see the video is still there. This mean the back lights are out. If you do not see the video it may be another problem

I have a red blinking power light. When turning on the TV with the remote is flashes green then returns to the red power light. I have tried the reset several times and have unplugged for several minutes but the set will not come on.

What do three blinks of the power light mean on my Sharp Aquos LC-C5262U? I cannot power up my display.
